摘要: A broadband powerline communication system makes use of knowledge of the spectrum characteristics of a local radio environment in order to improve system performance. A determination is made of the spectrum characteristics of a radio environment in the vicinity of the broadband powerline communication system that is transmitting data on modulated carrier frequencies. In order to avoid interference, certain ones of the carrier frequencies otherwise used by the broadband powerline communication system may be selectively masked based on the determination. The spectrum characteristics may be determined 1) in advance and used to compile a configuration database comprising frequency masking parameters; 2) by monitoring the local radio environment using the transmitter/receiver nodes of the system; or 3) based upon receipt of an indication from a conflicting user that the user is experiencing interference. Various combinations of these spectrum characteristic determination techniques may also be used.

摘要: Multiple-input/multiple-output (MIMO) antenna technology is used in a point-to-point radio link to provide higher data rates than would otherwise be achievable in a similar system that did not use MIMO antenna technology. Particular embodiments of the invention implement channel coding, dual polarization, adaptive receiver combining and adaptive power control.
